Pull '96 Suburban Rear Driveline?

Our '96 K2500 Suburban sounded funny to me last night. I crawled underneath and found the differential running hot. Yes, it's full of gear lube; the lube smells about right for used gear oil. My impression is I'm losing a pinion bearing. The rig has a bit over 191,000 miles right now.

I have to make it 60 miles to "Mr. Goodwrench." I'm not eager to haul it on my car trailer --- mostly because I just started taking the trailer down for wheelbearings and brakes.

I built a motorcycle carrier that goes in my receiver hitch and carries my Yamaha XT600. I figured to deliver the Suburban to the shop, then ride the bike home.

I was thinking I'd pull the live axles & stuff rags into the openings, drop the rear driveline, put the transfer case in 4Hi, and just drive it as a front wheel drive.

My friend just told me that if the rear driveline slips into the back of the transfer case with a spline -- as opposed to having its forward U-joint bolt to a yoke -- I couldn't pull the driveline without having the gear oil run out of the transfer case.

Is this the case?

Last time I drove the rig, 13 miles at 50 mph had the rear diff a bit warmer than I wanted to keep my hand on.

I'm thinking that if I just pull the live axles and run in 4Hi, the rear diff will still turn but will be unloaded. That should take the stress off the pinion bearing and keep the temperature down.

Does this make sense to y'all?

I decided to pull the live axles, but leave the rear driveline in. That unloads the rear end, and I'll run on the front end from here to Mr. Goodwrench. ;)

Hi,
You do know that without the axles in the lubricating oil for the wheel bearings will leak out
and driving 60 miles the bearings may burn out.

That's a valid concern. There sure was a bunch of gear oil in there when I pulled the axles and duct taped the hubs. I made it, though. Mr. Goodwrench was going to have it ready yesterday, but after I caught a ride down there, my cell phone told me some seals didn't show up and it would be Monday. Good thing I could meet my son and get a ride back home.

We got the warped rotors turned, too.

It's always something. At least it should be in good shape for our road trip to Iowa in September.

Ouch! $$$$

Yesterday, I enjoyed the motorcycle ride to the dealership to pick up the Suburban, a lot more than I enjoyed paying for it. ;) With rebuilt rear axle, front brake pads, and rotors turned, plus sales tax, it came to about $1,253.00. :eek:

Oh well, a new Suburban would be over $40K. I don't see a lot of new vehicles in my future.... ;)
